CROSS-REFERENCE TO RELATED APPLICATION
TECHNICAL FIELD
[0002] The present disclosure relates to the field of communication technology, in particular
to a control information transmission method, a control information detection method,
a network device and a User Equipment (UE).
BACKGROUND
[0003] In a conventional mobile communication system, a control channel needs to occupy
the entire system bandwidth, as shown in FIG. 1. When detecting the control channel
to acquire control information, a UE needs to detect the entire system bandwidth,
mainly resulting in the following problems. 1) Because the UE needs to detect the
entire system bandwidth, the detection complexity of the control information may increase
dramatically when the system bandwidth is relatively large. 2) The UE needs to be
provided with a large bandwidth for the reception of the control information, so it
is adverse to the flexible configuration of the bandwidth for the UE and the access
of a small-bandwidth UE.
[0004] In order to solve the above problems, in the standardization process, one method
is to divide a bandwidth available for the control channel within N available Orthogonal
Frequency Division Multiplexing (OFDM) systems into M control sub-bands or control
resource sets. In this way, the UE merely needs to detect the control information
in one control resource set, so as to reduce the detection complexity of the UE, as
shown in FIG. 2.
[0005] In a known scheme, the control resource sets are usually mapped to first one, two
or three symbols within one slot.
[0006] In a 5
th-Generation (5G) system, a multi-beam design is adopted so as to improve the coverage
performance. Within one synchronization period, a plurality of Synchronization Signal
(SS) blocks, i.e., Physical Broadcast Channel (PBCH) blocks, is used for the synchronization
of UEs. Each SS block corresponds to one beam. Here, the control resource set for
the transmission of some public system information (similar to System Information
Blocks (SIBs) in a Long Term Evolution (LTE) system) is defined as a public control
resource set. The optimal design of the public control resource set needs to be provided,
so as to improve the transmission reliability of the system information.
[0007] In a conventional transmission method, the public control resource set is placed
in first several symbols within one slot and multiplexed with the SS blocks in a time-division
manner.
[0008] In this method, in a multi-beam system scenario, a beam scanning operation needs
to be performed on each public control resource set. A beam direction is fixed, so
it is merely able to schedule the UEs within a beam range. When there is a relatively
large quantity of beams, the scheduling flexibility of the system may be significantly
reduced.
SUMMARY
[0009] An object of the present disclosure is to provide a control information transmission
method, a control information detection method, a network device and a UE, so as to
map a control resource set to same time-domain resources as a plurality of symbols
occupied by SS blocks, thereby to reduce the quantity of time-frequency resources
occupied during a beam scanning operation, improve the scheduling flexibility of the
UE, and reduce the detection complexity of the UE.

DETAILED DESCRIPTION
[0060] The present disclosure will be described hereinafter in conjunction with the drawings
and embodiments. The following embodiments are for illustrative purposes only, but
shall not be used to limit the scope of the present disclosure. Actually, the embodiments
are provided so as to facilitate the understanding of the scope of the present disclosure.
[0061] As shown in FIG. 3, the present disclosure provides in some embodiments a control
information transmission method which includes the following steps.
[0062] Step 31: mapping a control resource set for transmitting control information to at
least one RB adjacent to an RB occupied by an SS block in accordance with a predetermined
mapping mode. Here, the control resource set may be used for an initial access process
of a user or transmit public information (including one of scheduling system information,
paging information, power control information or any other public broadcast information).
The control resource set may also be called as public control resource set. The term
"public control resource set" defined herein is merely used for description, but shall
not be used to limit functions of the control resource set.
[0063] Step 32: transmitting the predetermined mapping mode to the UE, and transmitting
the control information to the UE on the at least one RB occupied by the control resource
set.
[0064] In the embodiments of the present disclosure, Step 31 may include mapping the control
resource set for transmitting the control information to at least one RB adjacent
to an RB occupied by a PSS in the SS block and to at least one RB adjacent to an RB
occupied by a PBCH in the SS block in accordance with the predetermined mapping mode.
[0065] To be specific, the at least one RB adjacent to the RB occupied by the PSS may include
at least one RB at a same time domain as, and at a different frequency domain from,
the RB occupied by the PSS. For example, the at least one RB at the same time domain
as, and at the different frequency domain from, the RB occupied by the PSS may include
a first CCE consisting of N consecutive RBs at the same time domain as the RB occupied
by the PSS and at a first frequency domain, and a second CCE consisting of N consecutive
RBs at the same time domain as the RB occupied by the PSS and at a second frequency
domain.
[0066] The at least one RB adjacent to the RB occupied by the PBCH may include at least
one RB at a same time domain as, and at a different frequency domain from, the RB
occupied by the PBCH. For example, the at least one RB at the same time domain as,
and at the different frequency domain from, the RB occupied by the PBCH may include
a third CCE consisting of N consecutive RBs at the same time domain as the RB occupied
by the PBCH and at a third frequency domain, and a fourth CCE consisting of N consecutive
RBs at the same time domain as the RB occupied by the PBCH and at a fourth frequency
domain. Here, N=6. Of course, N may be of any other value. In addition, the description
herein merely relates to a size relationship between the frequency in the first frequency
domain and the frequency in the second frequency domain, rather than positions of
the first frequency domain and the second frequency domain in a mapping pattern.
[0067] The PSS and the PBCH may be located at a same central frequency point and at different
time domains, and occupy different bandwidths. The PSS may occupy one OFDM symbol
in the time domain, and the PBCH may occupy three OFDM symbols in the time domain.
A frequency in the first frequency domain may be greater than a frequency in the frequency
domain where the PSS is located, and the frequency in the frequency domain where the
PSS is located may be greater than a frequency in the second frequency domain. A frequency
in the third frequency domain may be greater than a frequency in the frequency domain
where the PBCH is located, and the frequency in the frequency domain where the PBCH
is located may be greater than a frequency in the fourth frequency domain.
[0068] A specific design pattern of the control resource set will be described hereinafter
in conjunction with the drawings.
[0069] As shown in FIG. 4, in a 5
th-Generation (5G) New Radio (NR) system, the public control resource set may include
24 RBs for the transmission of a common control channel (6 RBs in each of the four
CCEs as specified in the 5G system), i.e., 6 RBs at either side of the PSS and 6 RBs
at either side of the PBCH (the 6 RBs adjacent to the PSS may occupy one OFDM symbol
in the time domain and occupy 6 RBs in the frequency domain, and the 6 RBs adjacent
to the PBCH may occupy three OFDM symbols in the time domain and occupy 2 RBs in the
frequency domain). In this pattern, each RB may be, for example, a Physical Resource
Block (PRB).
[0070] The 24 RBs may be divided into CCE0 (i.e., the first CCE), CCE1 (i.e., the second
CCE), CCE2 (i.e., the third CCE), and CCE3 (i.e., the fourth CCE). The serial numbers
CCE0 to CCE3 are merely used for illustratively purposes, but shall not be used to
limit the scope of the present disclosure. In addition, any other serial numbers may
also be applied.
[0071] In this pattern, when a subcarrier spacing is 15kHz, each RB may include 12 subcarriers
and have a bandwidth of 180kHz, and the PBCH in the SS block (a Secondary Synchronization
Signal (SSS) may occupy 12 RBs in the middle of a central symbol) may occupy 20 RBs
in the frequency domain and have a bandwidth of 3.6MHz. When the subcarrier spacing
is 30kHz, the PBCH may have a bandwidth of 7.2MHz. In addition, when the subcarrier
spacing is of any other value, the bandwidth occupied by the SS block may be extended
correspondingly.
[0072] In the embodiments of the present disclosure, the control resource set may include
the first CCE, the second CCE, the third CCE, and the fourth CCE. During the transmission
of the control information, Step 32 may include transmitting the control information
on the RBs occupied by the first CCE, the second CCE, the third CCE and the fourth
CCE in the control resource set.
[0073] In another possible embodiment of the present disclosure, Step 31 may include mapping
the control resource set for transmitting the control information to at least one
RB adjacent to the RB occupied by the PSS in the SS block and to at least one RB adjacent
to the RB occupied by the PBCH in the SS block in accordance with the predetermined
mapping mode.
[0074] To be specific, the at least one RB adjacent to the RB occupied by the PSS may include
at least one RB at a same time domain as, and at a different frequency domain from,
the RB occupied by the PSS. For example, the at least one RB at the same time domain
as, and at the different frequency domain from, the RB occupied by the PSS may include
the first CCE consisting of N consecutive RBs at the same time domain as the RB occupied
by the PSS and at the first frequency domain, and the second CCE consisting of N consecutive
RBs at the same time domain as the RB occupied by the PSS and at the second frequency
domain.
[0075] The at least one RB adjacent to the RB occupied by the PBCH may include at least
one RB at a same time domain as, and at a different frequency domain from, the RB
occupied by the PBCH. For example, the at least one RB at the same time domain as,
and at the different frequency domain from, the RB occupied by the PBCH may include
the third CCE consisting of N consecutive RBs at the same time domain as the RB occupied
by the PBCH and at the third frequency domain, and the fourth CCE consisting of N
consecutive RBs at the same time domain as the RB occupied by the PBCH and at the
fourth frequency domain.
[0076] In addition, Step 31 may include mapping the control resource set for transmitting
the control information to, in accordance with the predetermined mapping mode, number
M1 of adjacent RBs at a same time domain as the first CCE, number M2 of adjacent RBs
at a same time domain as the second CCE, number M3 of adjacent RBs at a same time
domain as a first OFDM symbol of the third CCE, number M4 of adjacent RBs at a same
time domain as a first OFDM symbol of the fourth CCE, number M5 of adjacent RBs at
a same time domain as a second OFDM symbol of the third CCE, number M6 of adjacent
RBs at a same time domain as a second OFDM symbol of the fourth CCE, number M7 of
adjacent RBs at a same time domain as a third OFDM symbol of the third CCE, and number
M8 of adjacent RBs at a same time domain as a third OFDM symbol of the fourth CCE.
The M1, M3, M5 and M7 RBs may be located at a same frequency domain, i.e., a fifth
frequency domain, the numbers of M2, M4, M6 and M8 of RBs may be located at a same
frequency domain, i.e., a sixth frequency domain, a frequency in the fifth frequency
domain may be greater than the frequency in each of the first frequency domain and
the third frequency domain, and a frequency in the sixth frequency domain may be smaller
than the frequency in each of the second frequency domain and the fourth frequency
domain.
[0077] Here, the description merely relates to a size relationship among the frequencies
in the first frequency domain, the second frequency domain, the third frequency domain
and the fourth frequency domain, rather than positions of the first frequency domain,
the second frequency domain, the third frequency domain and the fourth frequency domain
in a mapping pattern.
[0078] In some possible embodiments of the present disclosure, the number of M1 and M3 of
RBs may form a fifth CCE, the number of M2 and M4 of RBs may form a sixth CCE, the
number of M5 and M7 of RBs may form a seventh CCE, and the number of M6 and M8 of
RBs form may an eighth CCE. N=6, and M1=M2=M3=M4=M5=M6=M7=M8=3.
[0079] Another design pattern of the control resource set will be described hereinafter
in conjunction with the drawings.
[0080] As shown in FIG. 5, in the 5G NR system, the public control resource set may include
totally 48 RBs (6 RBs in each of the eight CCEs as specified in the 5G system), i.e.,
6 RBs at either side of the PSS, 6 RBs at either side of the PBCH (the 6 RBs adjacent
to the PSS may occupy one OFDM symbol in the time domain and occupy 6 RBs in the frequency
domain, and the 6 RBs adjacent to the PBCH may occupy three OFDM symbols in the time
domain and occupy 2 RBs in the frequency domain), 12 RBs adjacent to the first CCE
and the third CCE, and 12 RBs adjacent to the second CCE and the fourth CCE. In this
pattern, each RB may be, for example, a PRB.
[0081] The 24 RBs adjacent to the PSS and the PBCH may be divided into CCE0, CCE1, CCE2
and CCE3, and the 24 RBs adjacent to the first CCE, the second CCE, the third CCE
and the fourth CCE may be divided into CCE4 (i.e., the fifth CCE), CCE5 (i.e., the
sixth CCE), CCE6 (i.e., the seventh CCE), and CCE7 (i.e., the eighth CCE).
[0082] It should be appreciated that, the serial numbers CCE0 to CCE3 and CCE4 to CCE7 are
merely used for illustratively purposes, but shall not be used to limit the scope
of the present disclosure. In addition, any other serial numbers may also be applied.
[0083] In addition, in this pattern, when a subcarrier spacing is 15kHz, each RB may include
12 subcarriers and have a bandwidth of 180kHz, and the PBCH in the SS block (the SSS
may occupy 12 RBs in the middle of a central symbol) may occupy 20 RBs in the frequency
domain and have a bandwidth of 3.6MHz. When the subcarrier spacing is 30kHz, the PBCH
may have a bandwidth of 7.2MHz. In addition, when the subcarrier spacing is of any
other value, the bandwidth occupied by the SS block may be extended correspondingly.
[0084] In the embodiments of the present disclosure, the control resource set may include
the first CCE, the second CCE, the third CCE, the fourth CCE, the fifth CCE, the sixth
CCE, the seventh CCE and the eighth CCE. During the transmission of the control information,
Step 32 may include: transmitting the control information on the RBs occupied by the
first CCE, the second CCE, the third CCE and the fourth CCE in the control resource
set; and/or transmitting the control information on the RBs occupied by the first
CCE, the second CCE, the third CCE, the fourth CCE, the fifth CCE, the sixth CCE,
the seventh CCE and the eighth CCE in the control resource set.
[0085] In some possible embodiments of the present disclosure, on the basis of Steps 31
and 32, the control information transmission method may further include Step 33 of
transmitting a multiplexing mode of the control resource set and the SS block to the
UE, and the multiplexing mode may include time-division multiplexing or frequency-division
multiplexing.
[0086] To be specific, the multiplexing mode of the control resource set and the SS block
may be transmitted to the UE through semi-static indication. The semi-static indication
may include indicating the PBCH through one bit, or Radio Resource Control (RRC) signaling
configuration.
[0087] According to the embodiments of the present disclosure, the control resource set
for transmitting the control information may be mapped to the at least one RB adjacent
to the RB occupied by the SS block in accordance with the predetermined mapping mode,
and then the predetermined mapping mode may be transmitted to the UE and the control
information may be transmitted to the UE on the at least one RB occupied by the control
resource set. Through mapping the control resource set to a plurality of symbols at
the frequency domain adjacent to the SS block, it is able to reduce the quantity of
time-frequency resources for the beam scanning operation. In addition, it is merely
necessary to detect the physical resources occupied by the control resource set, rather
than the entire system bandwidth or the sub-band bandwidth, so it is able to simplify
the detection complexity of the UE.
[0088] In addition, the multiplexing mode of the control resource set may be transmitted
to the UE, and the multiplexing mode may include the time-division multiplexing or
the frequency-division multiplexing. In this way, it is able to improve the user scheduling
flexibility.
[0089] As shown in FIG. 6, the present disclosure further provides in some embodiments a
control information detection method which includes: Step 61 of receiving a predetermined
mapping mode from a network device, the predetermined mapping mode being a mapping
mode in which a control resource set for transmitting control information is mapped

domain, and a second CCE consisting of N consecutive RBs at the same time domain as

by the PBCH may include a third CCE consisting of N consecutive RBs at the same time
domain as the RB occupied by the PBCH and at a third frequency domain, and a fourth
CCE consisting of N consecutive RBs at the same time domain as the RB occupied by
the PBCH and at a fourth frequency domain.
[0093] In some possible embodiments of the present disclosure, the PSS and the PBCH may
be located at a same central frequency point and at different time domains, and occupy
different bandwidths. The PSS may occupy one OFDM symbol in the time domain, and the
PBCH may occupy three OFDM symbols in the time domain. A frequency in the first frequency
domain may be greater than a frequency in the frequency domain where the PSS is located,
and the frequency in the frequency domain where the PSS is located may be greater
than a frequency in the second frequency domain. A frequency in the third frequency
domain may be greater than a frequency in the frequency domain where the PBCH is located,
and the frequency in the frequency domain where the PBCH is located may be greater
than a frequency in the fourth frequency domain.
